Delx Commerce — Seeded Train/Test Split
x402
Delx Commerce — Seeded Train/Test Split is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).
Deterministically splits a list of integer items into train and test sets using a reproducible seed and a specified test fraction.

How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing 'train' and 'test' arrays of integers, the operation name, status ('pass'), and an evidence block including a SHA-256 hash of the input, a flag confirming no data was retained, and the count of external calls made — providing verifiable, auditable proof of the computation.
Example use cases
Reproducible ML dataset partitioning
“I have the item indices [1, 2, 3, 4, 5, 6, 7, 8] and I want to split them into train and test sets with 25% going to test. Use seed 'run-2024-a' so I get the same split every time I run this experiment.”
Verifiable agent pipeline data split
“Partition this list of record IDs [10, 20, 30, 40, 50, 60] into training and test groups using seed 'pipeline-seed-99' and a test fraction of 0.3 — I need cryptographic evidence that no data was retained.”
Consistent cross-validation fold seeding
“Split [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] into train and test with seed 'fold-1' and test fraction 0.2, then do the same with seed 'fold-2' — I'm building reproducible cross-validation folds for my model.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/seeded-train-test-split?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, reproducible, and verifiably auditable train/test split for a small integer dataset (up to 256 items) — especially in automated agent pipelines where cryptographic evidence of in-memory-only processing and no external calls matters. Prefer it over local random splits when reproducibility across machines or auditability is required and pay-per-call microtransaction economics fit your workflow.
Side effects
- Invalid or missing test_fraction (e.g. outside 0-1 range) may cause a validation error
- Items array exceeding 256 elements returns a schema validation error
- Seed string exceeding 8192 characters is rejected
- Payment failure (insufficient USDC balance) returns HTTP 402
- Malformed request body returns a 400-level error
